' Application filed'April 9, 1926. Serial No. 100,890.

My present invention relates to improvements in-sack jiggersfor use in connection with the process of filling sacks, bags or other portable receptacles with material,

such as grain, to insure filling of the recept-acle to its maximum capacity. I As is well known in the art, the sacks or bagsemployed for packaging grain are expensive, and if the sack is notfilled to its capacity a loss is entailed because of the use'of an increased number of sacks. The device or apparatus of my inventionis' designed'to agitate the sack as it is being filled, and parts of the apparatus are so' constructed,

as to insure filling the sack with grain to its full or maximum capacity, as the grain is discharged from a threshing machine, or from bulk storage. By the utilization of the apparatus of my invention, one or more sacks, while held in upright. position, are

agitated by imparting thereto a vertical reciprocation, and the carrier or supporting platform of the sack is so constructed asto insure proper and equal distribution of thegrain over the entlre area of the interior of the sack as the latter is being filled.

' The invention consists in certain novel combinations and arrangements of .parts whereby one or more of the units of the apo paratus may be utilized, and in featuresinvolved intheconstruction and operation of the apparatuses will'hereinafter be more fully pointed out and claimed. I

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein the parts are combined and arranged according to the best mode I'have thus far devised for the practical application of the principles of my invention.

Figure 1 is a view in side elevation of the apparatus of my invention, showing two units in operative relation to a pair of grain discharge spouts, with one of the units however elevated to out of use position.

Figure 2 is an end view of the apparatus of Figure 1.

Figure 3 is an enlarged, vertical, transverse sectional view as at line 33 of Figure 1.

Figure 4 is a detail sectional view similar to Figure 3 but with the platform raised by the detent to prevent reciprocation, or illustrating the apparatus as seen from the right in Figure 1. Figure 5 is a detail perspective view.

In carrying out my invention the apparatus is preferably made portable in order that it may be moved from place to place as desired, and for this purpose the two longitudinal beams or base bars 1 and2 may be used as skids. The base bars are preferably of wood and of suitable length and provided at suitable intervals with transverse braces or cross bars 3, to form a rigid support for the several guide frames, two of which are here illustrated as composed :of upright angle plates land horizontal plates or strap-irons 5. Four upright angle plates and the connecting horizontal plates or bars 5 are used to form-each of the rectangular In guideframes, the uprights 4 beinglocated at the four-corners of'the rectangular frame. Above the guide frames and supported there; from are arranged'pairs of metal posts 6 of suitable height and the upper ends of these 1:; pairs of posts are provided with fixed, horizontally disposed, arcuate straps or ring sections 7, 7" each provided with suspending hooks 8. The posts and arcuate plates form sackholders and two sacks S and S'are shown as suspended from thehooks of the supports 7 and 7 between the posts 6.

In Figure l'two units are illustrated,'the mechanism for agitating the sacks being duplicated, and the sacks are filled with grain from a pair of discharge spouts 9 and '10 that diverge fromthe grain pipe 11 receiving a supply of grain from a suitable source. By means of the pivoted gate shown in dotted lines and controlled by the handle 12 in Figure 1 the supply of grain may be directed to either of the sacks, or permitted to flow into both of the sacks simultaneously.

In fillingand agitating the grain sacks they are suspended from the hooks of the sack holders and their bottoms are supported on the rectangular, fiat, platforms 13 and 14 which are adapted to reciprocate vertically and are guided in their movements, at their four corners by the uprights 4 forming the guide frames for the platforms. On their upper surfaces or faces these platforms are fashioned with crowns as 15 which slope or decline from their highest central point I toward their edges in order that the bottom of the grain sack may be elevated at its central point and slope downwardly and outwardly, for the purpose of uniformly and properly distributing the grain as it flows into the sack.

The platforms are elevated mechanically by a positive cam action and fall by gravity for imparting the agitating motion to the sacks, and the elevating motion of the plat-.

ley 18 thereon (shown in Figure 1) from a suitable source of power.

Each platform is provided with guide in the form of a crank rod '19 which is loosely retained in bearing straps 20 secured at the underside of the platform, and the journal ends 21 of these crank rods are supported in bearing straps 22 bolted or riveted rat the outer side of two of the nip-rights 4 of the guide frame.

These crank rods or pivoted link-s permit the vertical reciprocating movement of the platforms, guide the platforms, and assist in holding them against displacement while retaining them in proper operative position.

The oam shaft or driving shaft is located below the platforms and vas here shown is provided with a pair of cam disks 2?) and 24L leach located below the center of a platform and in position to frictionally engage against a cam plate or wear plate 25 secured .at the underside of the platform. It will be apparent that as the cam shaft is revolved con- :tinuously the rotating cams will positively lift the platforms and alternately permit them to fall by gravity, thus accomplishing the reciprocation of the platforms to agitate the sacks and grain flowing therein to secure proper filling of the sacks to their maximum capacity.

If it is desired .to retain the platforms, :or one of them, out of operative position with relation to the cams or cam, a detent 26 is turned .to upright position as shown in Figure 4 to engage against the bottom face of the platform and retain the latter in its ele vated position. The detent is in form of a crank arm, pivoted in bearings 27 on the guide frame and provided with a handle 28 Each platfornnis equipped with one of the detents and one or the other of the platforms loe thus rendered inoperative when desired, as it will be apparent that the cam or cams may revolve without contact with the wear plate or cam plate on the platform.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a supporting frame and ,a stationary sack holder thereon, of a reciprocable platform and a pivoted guide link connecting said frame and platform, means for reciprocating the platform, and means for elevating said platform to inoperative position.

.2. The combination with a fixed supporting frame and a stationary sack holder thereon, of a reciprocable platform and operating means therefor, a crank-shaped link pivotal'ly connecting said platform and frame, and .a crank-shaped detent pivoted in said frame adapted to elevate the platform to inoperative position.

3. The combination with a fixed rectangular shaped supporting frame comprising corner-uprights and horizontal brace lea-rs, .of a rectangular platform reciprocable in said frame, a crank shaped link pivotally connecting the platform and frame, a cam- :shaft and cam thereon for actuating said platform, and a crank shaped detent pivoted in said fame and adapted to elevate the platform .to inoperative position.

In testimony whereof I aflix my signature.

HENRY G. WILLIAMS.
